Add A New Weapon

Add A New Weapon

First open wl_def.h and search for SPR_CHAINREADY you should see something like this:

SPR_CHAINREADY,SPR_CHAINATK1,SPR_CHAINATK2,SPR_CHAINATK3,
SPR_CHAINATK4,

for the sake of the arugment i called it Plasma for a new weapon: below this add:

SPR_PLASMAREADY,SPR_PLASMA1ATK1,SPR_PLASMAATK2,SPR_PLASMAATK3,
SPR_PLASMAATK4,

Then scroll down and look for this:

#define NUMWEAPONS 5
typedef enum {
wp_knife,
wp_pistol,
wp_machinegun,
wp_chaingun
} weapontype;

modify it to this:

#define NUMWEAPONS 6
typedef enum {
wp_knife,
wp_pistol,
wp_machinegun,
wp_chaingun,
wp_plasma
} weapontype;

Now open up wl_draw.c and look for this:

int weaponscale[NUMWEAPONS] ={SPR_KNIFEREADY,SPR_PISTOLREADY
,SPR_MACHINEGUNREADY,SPR_CHAINREADY};

modify it to this:

int weaponscale[NUMWEAPONS] = {SPR_KNIFEREADY,SPR_PISTOLREADY
,SPR_MACHINEGUNREADY,SPR_CHAINREADY,SPR_PLASMAREADY};

Now open up wl_agent.c and look for this
struct atkinf
{
char tics,attack,frame; // attack is 1 for gun, 2 for knife
} attackinfo[4][14] =

{

{ {6,0,1},{6,2,2},{6,0,3},{6,-1,4} },
{ {8,0,1},{8,1,2},{8,0,3},{8,-1,4} },
{ {6,0,1},{6,1,2},{6,3,3},{6,-1,4} },
{ {6,0,1},{6,1,2},{6,4,3},{6,-1,4} },

};

modify it to this

{
char tics,attack,frame; // attack is 1 for gun, 2 for knife
} attackinfo[5][14] =

{

{ {6,0,1},{6,2,2},{6,0,3},{6,-1,4} },
{ {8,0,1},{8,1,2},{8,0,3},{8,-1,4} },
{ {6,0,1},{6,1,2},{6,3,3},{6,-1,4} },
{ {6,0,1},{6,1,2},{6,4,3},{6,-1,4} },
{ {8,0,1},{8,1,2},{8,0,3},{8,-1,4} },

};

keep scrolling down till u get to this:
void CheckWeaponChange (void)
{
int i,buttons;

if (!gamestate.ammo) // must use knife with no ammo
return;

for (i=wp_knife ; i<=gamestate.bestweapon ; i++)
  if (buttonstate[bt_readyknife+i-wp_knife])
  {
   gamestate.weapon = gamestate.chosenweapon = i;
   DrawWeapon ();
   return;
  }
}

remove this entire code it is pointless... add this

void CheckWeaponChange (void)
{
int i,buttons;

switch (LastScan)
  {
  case 2:
   LastScan=0;
   if (gamestate.bestweapon >= wp_knife)
   gamestate.weapon = gamestate.chosenweapon = wp_knife;
   break;
  case 3:
   LastScan=0;
   if (gamestate.bestweapon >= wp_pistol)
   {
   gamestate.weapon = gamestate.chosenweapon = wp_pistol;
   DrawAmmo ();
   }
   break;
  case 4:
   LastScan=0;
   if (gamestate.bestweapon >= wp_machinegun)
   {
   gamestate.weapon = gamestate.chosenweapon = wp_machinegun;
   DrawAmmo ();
   }
   break;
  case 5:
   LastScan=0;
   if (gamestate.bestweapon >= wp_chaingun)
   {
   gamestate.weapon = gamestate.chosenweapon = wp_chaingun;
   DrawAmmo ();
   }
   break;
  case 6:
   LastScan=0;
   if (gamestate.bestweapon >= wp_plasma)
   {
   gamestate.weapon = gamestate.chosenweapon = wp_plasma;
   DrawAmmo ();
   }
   break;
  }

DrawWeapon();
}

Now that we have a new weapon it would be good if we could pick it up. So open wl_def.h again

Search for bo_spear you should see this:

bo_spear

add this

bo_spear,

bo_plasmagun

Now open up wl_act1.c

Scroll down till you see this:

{SPR_STAT_0} // puddle/water

Modify it to this:

{SPR_STAT_0,bo_plasmagun} //new weapon

Keeping scrolling down till you get to this bo_spear again.

You should see this:

case bo_spear:

add this below:

case bo_spear:

case bo_plasmagun:

Now in wl_agent.c search for bo_spear you should see this:

case bo_spear:
  spearflag = true;
  spearx = player->x;
  speary = player->y;
  spearangle = player->angle;
  playstate = ex_completed;

Below that add this:

case bo_plasmagun:
  SD_PlaySound (GETMACHINESND);
  GiveWeapon (wp_plasmagun);
  break;

Thats all pretty big huh *lol*
